Specification of Letters Patent.

Application filed June 1a, 1913. Serial no. 773,429.

' T all whom it may concern:

Be it known that I, JOSEPH S. DUNCAN, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain newand useful Improvements in Printin Devices,

' of which the following is a speci cation.

- the'type and 'which'will present only smooth and rounded surfacesalong the longitudinal margins thereof, thus obviating any tendency ofthe devices-to interlock or cling together.

ence to the following description when considered in connection witht-heaccompanying. drawings.

- Referring to the drawings-Figure 1 is a face view of a printing deviceembodying my Invent on; and Fig. 2 1s a transverse sectional' viev;takenpn the line 2-2 of "Fig. 1.

The printing device is preferably formed of asingle sheet of metalprovid ng a central printing portion 5 from the body of which theprinting characters 6 are stamped up, and the marginal spacing portions'7 adapted to space the devices apart to preventinjury to the printingcharacters when the devices are stacked or nested. The spacing portionsare formed by bending the metal along each longitudinal edge of the.printing portion first upwardly and outwardly to provide the inclinedportion 8, and then outwardly to form the flat face 9 which is disposedsubstantially in the plane with the printing faces of the printingcharacters 6. The metal outside the faces 9 isthen rolled downwardly'andinwardly,-the edges .11 being elevated slightly with respect to thelower faces 12 of the margins and terminating beneath the inclinedportion Sadjacent to the edges of the printing he invention in one ofits preferred em bodiments will be best understood by referthe entirelength of the device, above and portion andsubstantially in the plane ofthe print ng portion. The lower faces 13 of the margins, are, therefore,inclined upwardly from the lowest'point '12 and the edges 11 of themetal are protected so that no=corners or edges are exposed which mightengage with adjacent devices in a stack and cause the devices to'interlock or cling together.

,If it be desirable to-arran e thedevices' in accordance with a card inex system the spacing flanges'may be provided withv slots to receivesuitable index tabs, or, the index tabs may be, attached thereto in anywell.

known or referred manner.

It will e manifest that mynovel printing device presents no sharp,edgles or cor," ners, that the marginal spacing arfg es ex tend bothabove and below the normal plane the devices are stacked together thespacing flanges Wlll space the devices apart suffi; ciently' to preventcontact with or injury to of the metal and, that when a. number of theprintin faces of the printing characters on onedevlce by a contiguousdevice. I claim:

1-. A sheet meta-l printing device, comprising a printing portion,andlongitudinally disposed marginal spacing portions extend ing at theedges of the device, throughout below the lane of the metal fromwhich-the printing characters are formed, and having the longitudinaledges of the metal disposed contiguous to the printing portion of thedevice so as to be incapable of engaging with.

a similar device, the ends of said device between the spacing portionsbeing disposed in the original lane of the metal from which the deviceis formed.

2. A sheet metal printing device, comprising a printing portion havingprinting characters stamped up therefrom, and a longitudinally extendingmarginal spacing portion, the upper face of said spacing portion beingdisposed substantially in the plane of the printing faces of theprinting characters on said printing portion and the lower face of thespacing portion being disposed below the plane of the metal from whichthe printing characters are stamped up, the lower faces of said spacingportions being inclined upwardly from the margln of the device towardthe printing portion.

3. A sheet metal printing device, compris ing a. printing portion havingprinting char- 110 -acters stamped up therefrom, and longitudiupwardlyfrom the outer edges of the device toward the printing portion.

4. A sheet metal printing device, comprising a printing portion havingprinting characters stamped up from one face thereof, and longitudinallyextending marginal spacing portions comprising the margins of themetalbent upwardly substantially flush with the upper faces of said printingcharacters and rolled'downwardly below the plane of the lower face ofthe printing portion and then inclined upwardly to dispose the edges ofthe metal substantially in the plane of the printing portion and at theedges thereof.

.5. A sheet metal printing device, compris-.

ing a printing portion provided with print-' ing characters stamped upfrom the body of the metal, and marginal spacing portionsextending-above and below the body of the printing portion, said spacingportions consisting of the longitudinal margins of the metal sheet bentupwardly, then downwardly and'inwardly, and again upwardly to positionthe edges of the metal above the lower faces of the spacing portions.

' 6. A printing device comprising a metal sheet prgvided on one facewith printing characters stamped up from the body of the metal, themetal along the longitudinal mar gins of the device being bent todispose the upper faces of the margins at the edges of the device abovethe normal plane of the metal from which the characters are stain ed ,upand the lower faces of the margins e'low the normal plane of said metal,the edges of the metal terminating within the boundaries of the marginsand above the lower faces thereof.

7. A printing device comprising a strip of sheet metal having marginalspacing portions extending above and below the normal plane of the metalstrip along the longitudinal edges thereof, the metal forming saidspacing portions being elevated at the margins of the device above theoriginal plane and then bent downwardly and inwardly to dispose theedges-thereof beneath the elevated portions and substantially in theoriginal. plane of the metal.
